Provides module description page and examples of building render arrays.
Controllers that respond to a route should always return their content as a renderable array. See the arrays() method below as an example.

// unnecessary extra files.
//
// Learn more about attaching CSS and JavaScript libraries with the

// Renderable arrays have two kinds of key/value pairs: properties and
// children. Properties have keys starting with '#' and their values
// influence how the array will be translated to a string. Children are all
// elements whose keys do not start with a '#'. Their values should be
// renderable arrays themselves.
//
// This example defines a new element, 'simple', that contains two
// properties; '#markup' and '#description'. This is the quickest way to
// output a string of HTML.
$build['simple'] = [

// Additional properties can be used to further define the content. In this
// case '#prefix' and '#suffix' are being used to provide strings to add
// before, and after, the main content. This is useful because now the tag
// being used to wrap the block of content can be easily changed without
// having to worry about the content. Or, the tag can easily be left out
// during rendering if for example the content is being output as JSON.
//
// There is a set of common properties that can be used for all elements in
// a render array. These are defined by
// \Drupal\Core\Render\Element\RenderElement. Most elements also have
// additional element type specific properties.
//
// Figuring out what additional properties are available requires first
// determining what sort of render element you're dealing with. Look for the
// presence of one of these properties to start:
// - #markup, or #plain_text: These are the simplest render arrays, and are
// used to display simple strings of text. In addition to the common set
// of properties available for all elements #markup elements can use the
// #allowed_tags property, an array of additional tags to allow when the
// HTML string is run through \Drupal\Component\Utility\Xss::filterAdmin()
// to strip out possible XSS vectors.
// - #theme: The presence of #theme indicates that the array contains data
// to be themed by a particular theme hook. The available properties will
// depend on the specific theme hook. See the example below for more about
// determining what properties to use.
// - #type: The presence of #type indicates that the array contains data and
// options for a particular type of "render element" (for example, 'form',
// 'textfield', 'submit', for HTML form element types; 'table', for a
// table with rows, columns, and headers). The additional properties will
// depend on the render element type, and are documented on the class that
// defines the element type.

// As an example take a look at the code in

// determine what element type specific properties exist is to read the
// documentation for the class that defines the element type. Don't forget
// that it will also inherit properties used by any class it is extending.
//
// There are two types of render element types:
// - Generic elements: Generic render element types encapsulate logic for
// generating HTML and attaching relevant CSS and JavaScript to the page.
// These include things like link, table, and drop button elements.
// - Form elements: Most of the render element types provided by core
// represent the various widgets you might use on a form. Text fields,
// password fields, and file upload buttons for example. These elements
// are intended to be used in conjunction with a form controller class

// on form elements check out the fapi_example module.
